Area=150sqm
I hope this will help you
please add it to brain list

Answer 2

Answer:

2598 m²

Step-by-step explanation:

Ratio = 3:5:7

Let the ratio constant be x

Therefore the sides are 3x , 5x , 7x

Perimeter given is 300m

So ,3x + 5x + 7x = 300

=>15x = 300

=>x = 300/15

=>x = 20

Therefore ,we the sides are 60,100,140

Now s =60+100+140/2

=> 150

Area = √s(s-a)(s-b)(s-c)

Area = √150 (150-60)(150-100)(150-140)

Area = √150(90)(50)(10)

Area = 2598 m² approx
